The complexity of multi-vendor multi-edition systems


Recent IEC 61850Interoperability Panels/Demonstrations

• UCA: IEC 61850 IOP in April 2011

• UCA: IEC 61850 IOP in October 2013

• Cigre: IEC 61850 IOP in 2014

• UCA: IEC 61850 IOP in October 2015

• UCA: Scheduled IEC 61850 IOP in October 2017


IEC 61850 Interoperability 2011

• Report: IEC 61850 IOP, Paris, France UCAIug-63-111Rv1.pdf

– Issues found between vendor files• Incorrect initialized values

• Issues found between vendor implementations

– Support of Integer 128 issues

» Inability “to map/support such a value in the implementations memory/application”

• “Vendor A attempted to import an SCD file exported by Vendor B. A problem occurred.”

– Diagnosed to be an unsupported XML Namespace issue


IEC 61850 Interoperability 2013

• Report: http://www.ucaiug.org/Meetings/CIGRE_2014/USB%20Promo%20Content/

UCAIug/UCA%20Users%20Group%2061850%20IOP%20Report%2028012014f.pdf

– “Engineering efforts required to implement the standard in a substation are huge”

– “Grid operators are forced to use specific vendor tools that are not optimal in a multi-vendor environment and train staff to use a wide range of tools to configure the system”

– “A clear move by the market to a top-down approach using standardized third-party tools is needed”


IEC 61850 IOP 2013

• 61850 Standard Issues from the report:– SCL

• “ED.1/ED.2 co-existence in a single SCD file”

• “Client reporting subscription”

• “GOOSE subscription”

• “SV subscription”

– Networking• “VLAN Tag 0 support in switches”


Incorrect SCD/CID File Formats

• CIGRE 2014:

– Issues with Major Relay Vendor CID files

• Problem: Vendor tools create incorrect CID file formats– Issue: Found several instances of missing DOType, DAType,

ENUM, and ConnectedAP definitions

– Issue: Point IDs created to be too long and incompatible with certain 61850 server driver implementations <DOType cdc="ACD" id="SIPROTEC5_DOType_ACD_NonPhsSel_Without_DirRouting_V05.00.07_V02.00.00“>

• Solution: Vendor enhancement requests


Observations from IOP Results

• IOPs focus on newly-introduced features

• Communication interoperability has improved over time: Fewer problems observed

• SCL compatibility / interoperability seen is a major remaining area for improvement


Observation

• IEC 61850 specifies or uses several protocols

– MMS

• Client/Server “Vertical” communication

– GOOSE & SV

• Peer-to-peer “Horizontal” communication

– SCL

• Data sharing between tools

Determining the optimal application of unified configuration and documentation tools


IEC 61850:Engineering Process


IEC 61850: Engineering Tools

• Documentation

– The SCD file describes the substation in IEC 61850 SCL

– Tools can convert this information to present it in human readable format


IEC 61850: Engineering Tools


What functions are we looking for?

• Version-control

• Permission policies

• Approval processes and workflow

• Change Notifications

Configuration Management (CIP-010)

Configuration management as a natural extension of remote engineering access and password management


• A vast array of tooling and technology can be leveraged for working with the information

SCL Files are XML


• The CID schema can be extended for defining non-IEC 61850 devices (Modbus, DNP3, etc.) within the context of IEC 61850

• The CID schema can be extended to support equipment such as routers and switches

• Standard extensions currently in development

SCL Files are Extensible


Solving part of the problem

• IEC-61850 SCL helps with…• Considering all device configurations as

one holistic substation configuration

• Differencing two different configuration files

• Ensuring compatibility withnon-IEC 61850 devices

• Handle IT devices (routers, switches, and radios) in the same manner as OT devices

• Leveraging open standards


•Synchronization between the corporate environment and the substation

•Actively monitoring the devices in the substation

•Automatically extracting changed configurations from devices

Solving the other part of the problem


The Substation Configuration Description file (.SCD) by a Substation Engineering Modelling Tool

The SCD describes the entire substation configuration, including every IED, HMI, network switch, and router

1. SCD File Configuration


Because the SCD File is XML, the Corporate Device Manager has an

opportunity to configure itself based on the SCD file

2. The SCD File is Loaded into the Corporate Device Manager


Device Manger can:

• Automatically create a substation instance

• Place the SCD file under document control

• Automatically create all substation devices

• Automatically create substation and device

meta-data tags

• Extract per-device CID configuration files

• Place all CID files under document control

• Synchronize with other systems such as

certificate/key managers, historians, etc.

2. The SCD File is Loaded into the Corporate Device Manager


3. Transfer of SCD File to Substation Gateway

Electronic transfer ensures:

• SCD updates are always accessible at the substation

• The right configuration file is at the substation

• The right configuration file is at the substation

• The substation gateway can auto-configure itself

• The substation gateway can auto-configure the other

equipment in the substation




Configuring the substation gateway:


• Automatically build point references

• Establish which end devices have configurations ready to be deployed

• Establish which end devices have configurations ready to be deployed

• Automatically deploy those end device configurations



The Substation Gateway can actively poll and monitor the devices in the substation for out-of-band configuration changes

1. Front faceplate changes

2. Users accessing devices with vendor configuration software

4. Active Configuration Monitoring


If a change is detected, the Substation Gateway can extract the configuration from the device

In summary…

• Effective IEC 61850 Multi-Vendor and Multi-Edition Integration is possible

• The SCL platform can be used as a common data management platform– Extensible for non-IEC 61850 devices

– Readily managed to provide additional services
